Method to electrically connect chip with top connectors using 3D printing
A method for fabricating a three-dimensional (3D) electronic device. A liquid support material (e.g., an epoxy acrylate with a photoinitiator) is applied by a laser-induced forward transfer (LIFT) process to a printed circuit board (PCB) having one or more connectors and one or more electronic components thereon, and then cured to solid form by cooling and/or exposure to ultraviolet (UV) radiation. A layer of conductive material (e.g., a metal) is printed on the solidified support material by LIFT to electrically connect the one or more electronic components to respective ones of the connectors on the PCB. Subsequently, the layer of conductive material is dried by heating and metal particles in the conductive layer sintered using a laser beam. The assembly may then be encapsulated in an encapsulant.
